Abstract
PURPOSE To systematically appraise and summarize the available evidence about the diagnostic accuracy of ultrasound-guided fine needle aspiration biopsy (USFNA) for thyroid malignancy, and to explore the integration of these estimates with the probability of thyroid malignancy before USFNA. METHODS A comprehensive search of multiple databases from each database's inception to August 2014 was performed. Eligible studies included those that evaluated patients with thyroid nodules who underwent USFNA and subsequent evaluation by histopathology or long-term follow-up. RESULTS We identified 32 studies at moderate risk of bias evaluating the USFNA diagnostic characteristics for the diagnosis of thyroid malignancy. Results were imprecise and inconsistent across trials. The pooled likelihood ratio (LR) of thyroid malignancy for a benign USFNA result was 0.09 (95 % CI 0.06, 0.14; I (2) = 33 %), whereas the pooled LR for a malignant result was 197 (95 % CI, 68, 569; I (2) = 77 %). In the case of a suspicious for follicular neoplasm result, the pooled LR for malignancy was 0.6 (95 % CI, 0.4, 1.0; I (2) = 84 %) and 8.3 (95 % CI, 3.6, 19.2; I (2) = 89) for a result of suspicious for malignancy. CONCLUSION The available evidence regarding the diagnostic accuracy of USFNA warrants only limited confidence due to risk of bias, imprecision, and inconsistency. However, some USFNA results (benign, malignant) are likely very helpful, by significantly changing the pre-test probability of thyroid cancer.

Ganguly A, Burnside G, Nixon P. A systematic review of ultrasound-guided FNA of lesions in the head and neck--focusing on operator, sample inadequacy and presence of on-spot cytology service. Br J Radiol 2014; 87:20130571. [PMID: 25247346 PMCID: PMC4243210 DOI: 10.1259/bjr.20130571] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2013] [Revised: 08/05/2014] [Accepted: 09/22/2014] [Indexed: 11/05/2022] Open
Abstract
The objective of this review is to perform a systematic review of ultrasound-guided fine-needle aspiration (FNA) services for head and neck lesions with assessment of inadequacy rates and related variables such as the presence of immediate cytological assessment. A computer-based systematic search of articles in English language was performed using MEDLINE (1950 to date) from National Health Service evidence healthcare database and PubMed. Full texts of all relevant articles were obtained and scrutinized independently by two authors according to the stated inclusion and exclusion criteria. The primary search identified 932 articles, but only 78 met all the study criteria. The overall inadequacy rate was 9.3%, 16 studies had on-site evaluation by a cytopathologist/specialist clinician with a rate of 6.0%. In seven studies, a cytotechnician was available to either assess the sample or prepare the slides with an average inadequacy rate of 11.4%. In 1 study, the assessment was unclear, but the inadequacy rate for the remaining 54 studies, without immediate assessment, was 10.3%. The rate for the cytopathologist/specialist clinicians was significantly different to no on-site assessment but this was not found for assessment by cytotechnicians. The review suggests that the best results are obtained with a cytopathologist-led FNA service, where the pathologist reviews the specimen immediately, in relation to the clinical context, thereby deciding on adequacy and need for further biopsies. A systematic review looking at ultrasound-guided FNA of head and neck lesions has not been published previously.

Abstract
Minimal access surgery in the thyroid compartment has evolved considerably over the past 10 years and now takes many forms. This study examined the feasibility and reliability of minimally invasive thyroid surgery for the management of small benign thyroid lesions. A total of 68 patients with small thyroid nodules admitted to the Oncology Center of Mansoura University, Egypt, were enrolled in this prospective randomized trial. Patients were allotted to one of two procedures: minimally invasive video-assisted thyroidectomy (MIVAT) or minimally invasive open thyroidectomy using the Sofferman technique of strap muscle transection. Exclusion criteria were nodules > 4 cm, presence of thyroiditis, and thyroid gland volume > 20 ml. Preoperative diagnosis, operating time, blood loss, postoperative pain, complications, and cosmetic outcome were all evaluated. The MIVAT group included 35 patients, and the Sofferman group included 33 patients. The main preoperative pathology was a benign follicular lesion (70.5%), and the main postoperative final pathology was follicular adenoma (54.4%). The two groups were comparable regarding age, sex, and extent of thyroid surgery. Operating time was significantly longer in the MIVAT group (115.4 +/- 33.5 minutes) compared to the Sofferman group (65.6 +/- 23.7 minutes). The postoperative course was significantly less painful in the MIVAT group (p < 0.05). Although patients in the MIVAT group had smaller incisions (p < 0.05), the cosmetic outcome in the two groups was comparable. No long-term complication was encountered in either group. Two distinct approaches of minimally invasive thyroidectomy are now available and can be performed safely in selected patients. Despite some MIVAT advantages of less postoperative pain and slightly better cosmesis, minimally invasive open thyroidectomy offers an advantage of less operating time with comparable cosmetic results.

Abstract
UNLABELLED The aim of our study was to assess the accuracy and limitations of ultrasound guided fine-needle aspiration cytology (FNAC) of thyroid nodules. METHODS The usg-FNAC results of 245 patients with thyroid nodules, who afterwards underwent thyroid surgery or who died, and autopsies were carried out, and compared retrospectively with cytologic results. Patients with malignant cytologic conclusion without histological confirmation after surgery or autopsy were excluded from the study (9 persons). The usg-FNAC results were divided as follows: group 1: diagnosis of malignancy (n = 30), group 2: suspicion of malignancy (n = 28), group 3: benign (n = 126), group 4: inconclusive (n = 29). RESULTS Assuming the cytologic results of group 1 and group 2 were interpreted as being malignant and those of group 3 as being benign, the sensitivity, specificity and accuracy of usg-FNAC were 90 %, 85 % and 86 % respectively. Comparing the cytologic conclusions between a group of patients with follicular lesions and a subgroup of other lesions a statistically significant difference (p < 0,01) between both subgroups using Fisher's test was found. Sensitivity, specificity and diagnostic accuracy in subgroup of follicular lesions were low (71 %, 63 %, 67 %), while in the subgroup of other lesions were high (94 %, 86 %, 88 %). FNAC can specify the nature of focal lesion with high sensitivity, specificity and diagnostic accuracy in the cases of non-follicular lesions. Histological evaluation is required to specification of the nature in cases in which cytology is indicative of follicular proliferation.

Abstract
BACKGROUND Minimal access thyroid surgery, using various techniques, is increasingly being reported. The present study reviews our experience with thyroid surgery using a lateral focused mini-incision approach, and assesses its safety and feasibility. METHODS The study group comprised all patients undergoing minimal access thyroid surgery (MATS) during the period May 2002-May 2003. Data were prospectively gathered, including patient demographics, indication for surgery, operation performed, nodule size, final pathology, and complications. Exclusion criteria for this procedure included: family history of thyroid cancer, previous neck irradiation or surgery, carcinoma on fine needle aspiration, presence of significant thyroiditis, multinodular goitre, and nodule size >3 cm. The operation was carried out through a 2.5-cm lateral incision placed directly over the nodule, with exposure gained by dissecting the plane between the sternomastoid muscle and the lateral edge of the strap muscles. RESULTS Twenty-five patients underwent MATS, 22 women and three men. Nineteen patients underwent hemithyroidectomy, five underwent isthmectomy, and one underwent local nodule excision. The average measured incision size was 2.63 cm at the end of the procedure. The average nodule size was 2.2 cm, and the average thyroid lobe resected measured 4.7 cm in maximal length. Final pathology revealed benign nodules in 21 patients and four thyroid cancers (two follicular and two papillary). There was one wound infection and two patients had temporary recurrent laryngeal nerve neuropraxia. CONCLUSION Minimal access thyroid surgery is a safe and feasible alternative to open thyroid surgery in selected cases.

Abstract
INTRODUCTION The aim of the study was to investigate the current thyroid carcinoma (TC) incidence in Carinthia, a former iodine-deficient, goiter-endemic region in Austria with approximately 550,000 inhabitants from 1984 to 2001. Using age-cohort analysis we analyzed the TC incidence under the impact of two regional risk factors: the contamination of Austrian soils by the radioactive fallout in from Chernobyl 1986 and the increased iodination of table salt in a general program of goiter prophylaxis begun in 1991. To evaluate the characteristics of TC incidence, we compared the results of the periods 1984-1989, 1990-1995, and 1996-2001. RESULTS A total of 734 TC cases were diagnosed. Papillary, follicular, medullary, oxyphilic, and anaplastic TC accounted for 76%, 18%, 3%, 1%, and 2%, respectively. The female to male ratio was 3:1. The annual incidence rate increased by 8.05% in females and 11.6% in males. TC cases younger than 40 years of age accounted for 22.6%, with a rate increase of 18% per year in young males, the female-to-male ratio decreased from 8.3, 6.1, 2.7 younger than 40 in the compared periods. Along with a further increase in papillary TC incidence and papillary thyroid carcinoma (PTC) follicular thyroid carcinoma (FTC) ratio in the adult population, the ratio tended to decrease in the younger than 40-year-old population. T4 class TC and loco-regional lymph node involvement increased significantly. INTERPRETATION The observed changes in TC incidence, particularly in the young population, as in adults, could be linked to the abovementioned risk factors involved in the initiation and early growth of TC, and iodine may play a role in stimulating overall thyroid activity.
